NEETPhysicsMoving Charges and MagnetismMCQ+4 / −1
A galvanometer of 50 ohm resistance has 25 divisions. A current of 4 ×\times× 10−-−4 ampere gives a deflection of one division. To convert this galvanometer into a voltmeter having a range of 25 volts, it should be connected with a resistance of
  1. A
    2500 Ω2500\,\Omega2500Ω as a shunt
  2. B
    2450 Ω\OmegaΩ as a shunt
  3. C
    2550 Ω\OmegaΩ in series
  4. D
    2450 Ω\OmegaΩ in series
